SPECIFICATION forming part ofLetters Patent No. 634,730, dated October10, 1899.

Applieation filed August 23, 1899. Serial No, 728,248, (No model.)

To all whom, it may concern: 1

, Be it known that we, THoMAs J. HOWE, DAVID J. AMES, and HENRY N.LABARE, of. Owatonna, county of Steele, State of Minne= 5 sota, haveinvented certain new and useful Improvements in Gate-Valves for Ohurns,of which the following is a specification.

This invention relates to improvements in gate-valves designedespecially for use in churns, though applicable generallyio casks,barrels",hogsheads,tanks,or other receptacles; and the objects we .havein view are to provide a valve in which the valve-disk is adapted 'toautomatically conform itself to the valve-seat, so as to afford a tightjoint when the valve is closed.

Another object of the invention is to provide a gate-valve with astraight unobstructed passage and having no recesses or orifices thereinextending 0% from the main passage and liable to become filled orclogged with the material that is drawn from the receptacle upon whichthe valve is used.

Another object of the invention is to provide a valve of this kind witha self-adjusting disk, wherebya close fit of the valve-disk upon theseat is secured.

, Other objects of the invention will appear from the following detaileddescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is a partial section of 'a churn or other receptaclehaving our improved valve applied thereto. Fig. 2 is a section on line mw of Fig. 1. Fig. 3 is an elevation, looking at the inner end of thevalve. Fig. 4c is an outside end elevation of the valve.

In the drawings, '2 represents the valvecasing, which is preferablyacylindrical cast- 0 ing having a flange 3 formed integrally with itsouter end and flush therewith and having an inclined inner end 5,forming a valve-seat. A projection .7 is formed, preferably, integrallywith the valve-casing 5 and has a straight 5 hole through it to receivethe valve-operating stem 9. The Valve is in the form of a disk 11,having, preferably, a leather or other suitable covering 13 securedthereto by the central rivet 15, which secures the valve-disk I ll-tothe crank-arm 17 of the valve-stem 9.

The disk 11 preferably has an upturned lip 19 at one side, and theleather covering 13 is turned up and secured to this lip by means of arivet 21. This prevents i the leather from being rolled up as the valveis swung onto its seat. The rivet lfifits loosely in the crank-arm 17,so that the valve is self-adjusting, and thereby adapts itself to thevalve seat. The top of the disk 11 is preferably provided with thelugs23, which project upon either sideof the crank-arm 17, so as to preventthe disk 11 from turning on .or with the rivet 15. This causes the lip19 to move ahead in shutting the valve. The valve-stem 9 preferablypasses through a suitable stuff- 6 ing-box 25 in the projection 7, or asuitable packing might be used outside of said projection and around thevalve-stem, as preferred. A handle 27 is secured upon the valve-stem bymeans of a suitable nut 29. 7o Projections 31 are preferably providedupon the face of the, flange 3 to limit the movement of the handle 27.

The operation of the device is as follows: The valve-casing is insertedin a suitable opening extending through the wall of the churn, cask,tank, or other receptacle, as shown in Figs. 1 and 2 of the drawings.Whenthe valve is used with the lip 19, the disk and valve stem mnst beremoved before inserting the casing in the opening prepared for it, andthe disk and stem are then put in place from the inside of thereceptacle. Where access cannot be had from the inside of thereceptacle, the lip 19 is omitted, and the entire device may then be putinto place from the outside of the receptacle. The disk adj usts itselfto the surface of the valve-seat,

and it is forced onto said seat by means'of the crank-arm 1'7, the stem9, and the han- 9o dle or lever 27. By tighteningthe nut 29 the pressuremay be increased any desired amount on the valve-disk.

It will be seen that this gate-valve is exceedingly simple inconstruction. It is capable of beinginserted and adjusted from theoutside of the churn or other receptacle. It has a straight smoothunobstructed orifice [or the How of liquid from the churn 01' otherreceptacle, and the valve is capable of being very quickly operated,either for opening or closing. It will also be seen that this gate valveis so constructed that in case of its use in a churn none of the creamcan remain unohurned in the tube of the gate while churning to be lostin the buttermilk.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination, with the cylindricaleasing 2 having an inclined seat upon its inner end, of the swingingvalve-stem 9 provided with the crank 17 and the disk valve connected tosaid crank-arm and adapted to be seated upon the inclined inner end ofthe casing 5, for the purpose set forth.

2. The eombination, with the casing 2 havinga smooth-s11 rfaced orificeextending therethrongh and provided with the inclined valveseat 5 at itsinner end, of the rotatable valvestem 9 provided at its outer end with asuitable handle and at its inner end with the crank-arm 17-, and asuitable valve disk loosely connected to said crank-arm, for the purposeset forth.

3. The combination, with the casing 2 having the flange 3 and projection7 formed integrally therewith and provided with an inclined valve-seatat its inner end, of the retatable valve-stem 9 inonntedin saidprojection 7 and provided at its outer end with a suitable handle and atits inner end with a crank-arm, of the valve-disk provided with theupturned lip 19, asuitable facing secured to said disk and means forloosely connecting said disk to said erankarm,substantially asdescribed. I 4. The combination, with the casing 2 having an, inclinedinner end forming a valveseat, of the valve-stem 9 having a crank-arm atits inner end, avalve secured to said crankarm and means for adj nstingsaid valve-stem longitudinally and thereby adjusting said valve, for thepurpose set forth.

In testimony whereof we have hereunto set our hands this 16th day ofAugust, 1899. THOMAS J. HOWE. DAVID J. AMES. HENRY N. LABARE. Inpresence of MINNIE E. AMES, 7 FRANK LA BAREL
